Abstract
An asynchronous transfer mode digital document delivery system is provided. A customer premise unit is configured to permit a customer to order and receive a data stream. A buffer is coupled to the customer premise unit to store the data stream before transmitting the data stream to a customer. A server includes digital documents stored thereon for delivery to customers through a switched ATM network. A control mechanism is employed to control a data rate of the data stream between the server and the buffer to ensure maintenance of a steady data stream from the customer premise unit to a customer during a loss of a physical layer between the server and the customer premise unit.
Claims19
An asynchronous transfer mode digital document delivery system, comprising:
- a customer premise unit configured to permit a customer to order and receive a data stream;
- a buffer coupled to the customer premise unit to store the data stream before transmitting the data stream to a customer;
- a server having digital documents stored thereon for delivery to the customer through a switched ATM network;
- and
- means for controlling a data rate of the data stream between the server and the buffer to ensure maintenance of a steady data stream from the customer premise unit to the customer during a loss of a physical layer between the server and the customer premise unit.
A method for maintaining a data stream over an asynchronous transfer mode network, comprising the steps of:
- providing a customer premise unit configured to permit a customer to receive a data stream;
- storing a portion of the data stream in a buffer before transmitting the data stream to a customer;
- transmitting the data stream from a server through a switched ATM network;
- and
- controlling a data rate of the data stream between the server and the buffer to ensure maintenance of a steady data stream from the customer premise unit to a customer during a loss of a physical layer between the server and the customer premise unit.
